This article, titled "Intracranial Extra-Axial Tumors Invading the Extracranial Parapharyngeal Space (PPS): A Systematic Review," provides a comprehensive review of the clinical presentation, radiological features, operative techniques, and postoperative morbidity of intracranial brain tumors that invade the parapharyngeal space (PPS). The authors conducted a systematic review and meta-analysis of the current literature to gather information on peri-operative complications, such as cranial nerve palsies, vascular injury, CSF leakage, infections, mortality rate, and extent of resection. The article concludes that the involvement of PPS by intracranial neoplasms is rare, and limited data is available on this condition. The authors provide a detailed summary of presenting symptoms and management options, as well as discuss the surgical implications and morbidity burden of addressing neoplasms in the PPS.
